The purpose of this study is to determine the effects of ecopipam in patients with Lesch-Nyhan Disease (LND). Ecopipam specifically blocks the actions of one chemical in the brain that helps nerves talk to one another; ecopipam does this by stopping the chemical (dopamine) from binding to one of its family of receptors (i.e, the D1 family). LND is a very rare genetic disease. The sponsor is doing this study to find out what side effects ecopipam causes in LND patients, and whether ecopipam may be able to relieve the self-injurious behaviors seen in these patients.

To assess the possibility that treatment with Kuvan (a form of tetrahydrobiopterin) will lessen the abnormal behavior and/or neurology commonly found in Lesch-Nyhan disease (LND); to asses...
OBJECTIVES: I. Determine the effects of aminoimidazole carboxamide riboside (AICAR) on hematologic manifestations of Lesch-Nyhan disease. II. Assess the behavioral and neurological bene...
The primary objective of this study is to evaluate the efficacy and tolerability of ecopipam in reducing stuttering symptoms. It is hypothesized that ecopipam effectively reduces stutteri...

Alcohol abuse and dependence are very prevalent and result in significant morbidity, mortality and cost to society (Harwood 2000). Pharmacotherapies to assist with alcohol dependence consi...
Patients with deficient hypoxanthine-guanine phosphoribosyltransferase (HPRT) activity present hyperuricemia and/or hyperuricosuria, with a variable degree of neurological manifestations. Hyperuricemi...
Humans have lost the ability to convert urate into the more soluble allantoin with the evolutionary inactivation of three enzymes of the uricolytic pathway. Restoration of this function through enzyme...
Behçet's disease is a multi-system disease with inflammatory infestations, in particular of the small and middle arteries and veins. Histologically, the disease presents with the image of leukocytocl...
Inflammatory bowel disease (IBD) is characterized by uneven disease courses with various clinical outcomes. A few prognostic markers of disease severity may help stratify patients and identify those w...
An enzyme that catalyzes the conversion of 5-phosphoribosyl-1-pyrophosphate and hypoxanthine, guanine, or 6-mercaptopurine to the corresponding 5'-mononucleotides and pyrophosphate. The enzyme is important in purine biosynthesis as well as central nervous system functions. Complete lack of enzyme activity is associated with the LESCH-NYHAN SYNDROME, while partial deficiency results in overproduction of uric acid. EC 18.104.22.168.
Excessive URIC ACID or urate in blood as defined by its solubility in plasma at 37 degrees C; greater than 0.42mmol per liter (7.0mg/dL) in men or 0.36mmol per liter (6.0mg/dL) in women. This condition is caused by overproduction of uric acid or impaired renal clearance. Hyperuricemia can be acquired, drug-induced or genetically determined (LESCH-NYHAN SYNDROME). It is associated with HYPERTENSION and GOUT.
An inherited disorder transmitted as a sex-linked trait and caused by a deficiency of an enzyme of purine metabolism; HYPOXANTHINE PHOSPHORIBOSYLTRANSFERASE. Affected individuals are normal in the first year of life and then develop psychomotor retardation, extrapyramidal movement disorders, progressive spasticity, and seizures. Self-destructive behaviors such as biting of fingers and lips are seen frequently. Intellectual impairment may also occur but is typically not severe. Elevation of uric acid in the serum leads to the development of renal calculi and gouty arthritis. (Menkes, Textbook of Child Neurology, 5th ed, pp127)
Animate or inanimate sources which normally harbor disease-causing organisms and thus serve as potential sources of disease outbreaks. Reservoirs are distinguished from vectors (DISEASE VECTORS) and carriers, which are agents of disease transmission rather than continuing sources of potential disease outbreaks.
Analyses for a specific enzyme activity, or of the level of a specific enzyme that is used to assess health and disease risk, for early detection of disease or disease prediction, diagnosis, and change in disease status.
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
